3 Claims.

This invention relates to new and useful im.- provements in a dust suction device for cleaning furs, clothing and the like.

This application is an improvement over my Patent No. 2,047,787.

An important object of this invention is the construction of the combination brush and vibrator to efficiently perform its work, and the arrangement of mounting this brush and vibrator within the air duct of the device in a particular manner.

A further object of the invention resides in forming the combination brush and vibrator of two .distinct end sections separated by a pulley portion, and to drive this device by a belt extending over said pulley portion.

Still further the invention proposes to adjustably mount the ends oi the combination brush and vibrator so that it may be set at various tilted positions to obtain a. multiplicity of different degrees or" operation of the device. A ieaf ture of this adjustment resides in the fact that it may be pivoted about the driving pulley as a center so that there need be no changes as far as the driving unit is concerned, for the various adjustments possible.

Still further the invention proposes the provision of a plate formed with .a longitudinal slot and adapted to close the top opening in the inverted saucer-like casing, and having edge portions resting upon a flange surrounding said opening. When thus constructed it may be readily removed and replaced when desired, and in addition it may be adapted to hold down the air duct of the device.

A further object of the invention resides in the provision of a flange on the air duct which is adapted to rest beneath the :dange from the plate whereby the air duct may be smartly heldin position.

Still further the invention contemplates a novel association ci the blower with the air duct.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had tothe following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. 10 is a bottom view similar to Fig. 3 but showing a modied form of the device.

The dust suction device for furs, clothing and the like, according to this invention, includes an inverted saucer-like casing I0 adapted to be attached upon a table II and having a top opening I2. A plate I3 is formed with a longitudinal slot I4 and is adapted to partially close the top opening I2. This plate has an edge portion resting upon a flange portion I2a surrounding the opening I2 and projecting from the casing I. An air duct I5 is arranged within the casing i9 and extends completely across the slot I4. This air duct is formed with a flange I5 resting upon the flange I2a and disposed beneath the edge portion of the plate I3.

A blower I1 is mounted within the casing I0 and upon one side of the air duct I5. This blower has its suction intake I8 connected with the said duct I5 and has its pressure discharge I9 adapted to be connected with an air filter bag 25 (see Fig. '7). A combination brush and vibrator 2| is arranged within the air duct I5 adjacent and beneath the slot I4 and is adapted to brush and beat furs, clothing and other articles passed over the top of the casing. A means is provided for driving the combination brush and vibrator and includes an electric motor 22. This motor is also utilized to drive the blower I1.

An electric switch 23 is shown mounted upon one side of the saucer-like casing I0 and is for the purpose of controlling the motor 22. This specication does not disclose the wiring of the switch to the motor as it forms no part of the invention,

The plate I3 is held in position by several screws 24 passing through the plate and into the flange I2a. This plate is also formed with several openings 25 in the vicinity of the slot I4 and adapted to receivepegs 26 from a screen 21 adapted to be positioned over the opening I4. This screen is shown in dotand dash lines in Figs. 6 and 5.

The air duct I5 is of a much smaller width than the width of the opening I2 so that when the plate I3 isremoved, as shown in Fig. 2, the blower is exposed. A screen element 28 is extended across the suction inlet I8 of the blower. The blower I1 includes a casing I1a in which a blower rotor I1b is mounted. This rotor is taken on mounted upon the shaft 22a from the motor 22. The motor is mounted through one side of the casing I 0 and is supported upon a shelf 3U included for this purpose. This shelf is attached upon the side wall of the casing l0.

The combination brush and vibrator 2l comprises two distnct sections, the section 22a and the section 2lb separated by a pulley Zic. Each of the sections 2| f1 and 2lb comprises a cylindrical body portion from which two ange blades 2|d radially project. These blades are spaced from each other. Spaced 120 from these blades there is a bristle brush 2| e. The sections 2|a and 2lb are so arranged that the bristle brushes 2|d of the end sections are 180 from each other.

The combination brush and vibrator is mounted upon a shaft 32 which isadjustably supported at its ends, Each of the ends of the shaft 32 is rotative in bearing 33 which has a trunnion 3l!y swivelled in a block 35 vertically adjustable on tracks 36 mounted upon the sidewalls of the air duct l5. A plurality of set screws 31 are mounted on the tracks for abutting the blocks 35 to hold the blocks in adjusted positions.

It is possible to arrange the combination brwsh and vibrator so that it is level and acts universally throughout the length of the slot I4. If it is desired one of the blocks 35 may be adjusted slightly upwards and the other of the blocks slightly downwards so as not to change the relative distance between the pulley 2l and the motor shaft 22a, while at the same time changing the operation of the brush and vibrator at the opposite ends of the slot I4. Thus, more violent brushing and vibrating may be accomplished at one end of the slot than the other. It is thus possible to pass coarser materials over the coarser operating side of the brush and vibrator, and finer materials over the other side.

A belt 38 passes over the pulley 2|c and over a pulley 39 mounted on the shaft 22a. Thus, the motor 22 is capable of operating the combination brush and Vibrator.

In Fig. 8 an electric plug 40 is shown associated with a cable 4| which is connected with the motor 22.

In Fig. 10 a slightly modied form of the invention has been disclosed which distinguishes from the prior form merely in the construction of the blower outlet. In this form of the invention the blower outlet I9a is of elliptical shape, contrasted with the circular shape of the blower outlet I9 (see Fig. 3) in the prior form of the dev ice.

While I have illustrated and described the p-referred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope. of the invention as defined in the,4 appended claims. t
